Application filed June 1, 1817. Serial No. 172.287.

To alhohom it may concern: 1 Be it known that we, JAMES WORTHING- TON and WILLIAM WORTHINGTON, subjects of the King of Great Britain, residing at {Pleasant City, in the county of Guernsey and State of Ohio, have invented certain new and useful Improvements in Record- Cleanin Attachments for Phonographs, of which tie followin is a specification.

This invention re ates to an improved record cleaning attachment for phonographs and has as its primary object to provide a device of this character which may be connected with the tone arm of the phonograph for brushing the record as it revolves and freeing the record of dust or other foreign matter before coming in contact with the phonograph needle.

The invention has as a further object to provide a device of this character which may be connected to a honograph employing a goose-neck or croo in the tone arm for supporting the phonograph sound box or may be connected to a phonograph having a straight tone arm.

And the invention has as a still further object to provide an attachment of the above described characten wherein the brush will be both longitudinally and rotatably adjustable so that the said brush may with facility be properly positioned with respect to the needle of the phonograph.

Other and incidental objects will appear as the description proceeds and in the drawings wherein we have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views:

Figure 1 is a plan view showing our improved attachment applied to a conventional type of phonograph employing a goose-neck or crook or supporting the sound box of the phonograph,

Fig. 2 is a similar view showing our improved attachment applied to a conventional type of phonograph employing a straight tone arm,

Fig. 3 is a detail perspective view showing the parts of the device disconnected, and

Fig. 4 is a detail plan view of the dev ce.

In carrying out our invention, we employ a split attaching member or clip 10, the free ends of which are adjustably connected by a clamp screw 11. Depending from the lower side of the clip is a cylindrical shank or stem 12. This stem is, as particularly shown in Fig. 4., formed with angularly disposed flat faces 13 and 14 respectively. Mounted upon the stem 12 is a supporting member for the brush employed. This supporting member includes a sleeve 15 loosely fitted upon the stem 12 and e nipped with a binding screw 16 adjustable or engaging the stem to hold the sleeve at slidable and rotatable adjustment upon the stem. Extending laterally from the sleeve is an arm 17. Supported by this arm is a brush or cleaning element 18. The brush is formed with a body 19 of wood or other approved material and this body is recessed or cut away to receive a plate 20 secured to the brush body by screws or other suitable fastening devices. The plate 20 is longitudinally slotted to freely receive a headed screw 21' arranged with the head thereof engaged with the lower side of the plate and received within the recess in the brush body 19. This screw is loosely fitted through the outer extremity of the arm 17 and receives a thumb nut22 adjustable for clamping the brush in position.

In Fig.1 0 the drawings, we have shown our improved attachment applied to a conventional type of phonograph employing a goose-neck or crook for supporting the phonograph sound box. The phonograph includes the usual rotatabl table 23 upon which is mounted a record 24. Arranged to swing across the table is the tone arm 25 to the outer extremity of which is swingingly connected a goose-neck or crook 26. Mounted upon the outer end of the gooseneck is the sound box 27 carrying the stylus bar 28 which is equip ed with a needle 29. The clip 10 is first c amped by the clamp screw 11 about the gooseeneck 26 at a point substantially midway the ends thereof with the stem 12 pro iectin downwardly from the goose-neck. he sliaeve 15 of the brush supporting member is then adjusted upon the stem to a. position with the arm 17 thereof extending laterally from the goose neck in the direction of the sound box 27. When the sleeve is thus swung upon the stem 12, the clamp screw 16 will be brought opposite the list face 14 of the stem to engage therewith for securely holding the brush supporting member at adjustment. After the rush supporting member has thus been fixed, the brush 18 may then be adjusted upon the arm 17 by means of the screw 21 Ill) to occupy a position, when the needle 29 is was a);

rested upon the record 24, arranged in the rear of the needle to contact with the record. The vertical adjustment of the. brush is of course obtained by properly positioning the sleeve 15 of the brush supporting-member longitudinally upon the stem 12 while the lateral adjustment of the brush is obtained by sliding the screw 21 longitudinally within the slot of the plate 20. The brush may thus be readily positioned in the rear of the needle 29 to sweep the record and clean it of all dust or other foreign matter as the record is revolved upon the table .23. The necessity for the manual cleaning of the record before use thus overcome.

In Fig. 2 of the drawings, we have illustrated our improved device attached to a conventional type o f phonograph havin Y a straight tone arm. of the phonograph is indicated at 30 and mounted upon this table is the record 31. Arranged to swing across the table is the tone arm 32 upon the outer end of which is mounted the sound box Carried by the sound-box is th ,stylus 34 to which is con nected the need e 35 for engagement with the record. In mounting, the attachment, the clip 10 is first connected to the tone arm 32 in the rear of the sound box 33 with the stem 12 projecting beneath the tone arm. The sleeve 15 of the brush supporting member is then rotated upon the stem to a position with the arm 17 of the said member extendin forwardly beneath the tone arm toward t 0 sound box. With the arm thus disppsed, the binding screw 16 upon the sleeve will be arranged to confront the flat face 13'of the stem 12 to engage therewith for rigidly holding the sleeve at adjustment. After the brush supporting member has been thus arranged in position, the brush 18 is adjusted longitudinally with respect to the arm 17 of the said member to occupya proper position in the rear of the needle 35 to contact with the record 31. If desired, the brush may be further rotatably adjusted upon the arm 17 into angular relation to the tone arm 32 to assumeaposition with the length of the brush disposed radiall of the axis of rotation of the record 31. y thus positioning the brush, the bristles thereof will more readily, follow the grooves in the record for cleaning the record of all foreign matter as the record is revolved upon the table 30.

It will, therefore, be seen that we provide a particularly simple and eflicient construc- Li this figure, the ta )le including an attaching member, a rotatably adjustable cleaning element supporting member slidably adjustable vertically upon said first mentioned member, and a. cleaning element carried by the said last mentioned member.

2'. A device of the character described in element supporting ember carried thereby, and a cleaning elem nt carried by the said last mentioned member and slidably adjustable laterally thereon.

3. A device of the character described including an attaching member provided with a shank, a cleaning element supporting eluding an attachil g member, a cleaning member adjustable longitudinally upon the shank, a cleanin element, and means slidably and rotatab y connecting the said element with the said last mentioned member.

4. A device of the character described including an attaching member, a shank carried thereby, a sleeve vertically and rotatably adjustable upon the said shank and provided with a lateral arm, and a cleaning element carried by the said arm.

5. A device of the character described including an attaching member, a shank carried thereby, a cleaning element supporting member mounted upon the said shank and including an arm, a cleaning element includin a body, a slotted plate carried by the ha y, and means fitted through the slot in said plate and engaged with the arm for rotatably and slidably connecting thecleaning element ith the said arm.

U. A record 0 caning attachment for phonographs includin an attaching member connected with t e phonograph tone arm, a cleaning element supporting member carried by saii: first mentioned memberand adjustable thereon in a plane at right angles to the said arm, and a cleaning element carried by said last mentioned member and adjustable thereon to engage a record u on the phonograph for cleaning the recor In testimony; whereof we aiiix our signatures.
